  • Example III of this patent Another concern within the technology of this patent occurs when the snap-on cap is removed to facilitate replacement activity, thus exposing the bare area of the top of the used generator to the operator or patient, which has a stated temperature of 627 F. according to Example III of this patent.
  • a further concern noted in Example III of this patent is the apparent temperature of the oxygen at the exit orifice of the generator, which is near or at the stated 627 F. of the generator (canister) surface temperature, and the consequent improbability that a delivery tubing of normal length will cool this oxygen to near body temperature prior to reaching the mask for inhalation.
  • the primary object of this invention is to provide a lightweight, portable and safe dispenser for single medically pure oxygen producing generators capable of being instantly activated from a completely inert condition to deliver oxygen at a rate and temperature suitable for direct human inhalation.
  • a preferred embodiment of this invention utilizes the disposable tin can type chlorate-oxide generators disclosed in U. S. Patents 3,702,305 (Thompson) and 3,861 ,880 (Thompson) cited in related art, which provide a minimum of 90 standard liters of USP oxygen with the desired amount of water vapor at a rate of 6 liters per minute for 15 minutes.

  • Figure 2, Figure 3 and Figure 4 may be referred to together as covered by the following text.
  • Figure 2 shows a cutaway of the upper portion of the dispenser which includes a sectional view of the top web 12, made up of a plurality of equally spaced fingers 14 attached to the top of the cylindrical body by fasteners 13, generating radially from the center of the top web which holds the starting mechanism for the oxygen generator 15 depicted in-place ready for use.
  • the oxygen generator itself 15 is not shown with internal detail, and is instead in ⁇ corporated by reference in the related art section, as that covered within the disclosures of U.S. Patents 3,702,305 (Thompson); 3,725,156 (Thompson); 3,736, 104 (Thompson); 3,749,678 (Thompson); 3,806,232 (Thompson) and
  • U.S. Patent 3,725, 156 (Thompson), the disclosure of which is incorporated herein by reference.
  • One end of the tin can has a sealed orifice which is easily punctured to expose a plunger slidable in a sealed water-filled chamber which is punctured by a pin depending from the plunger when the plunger is depressed, or a vial which is fractured by the pin when the plunger is depressed.
  • the liberated water immediately, moistens the ignition cone material which activates the chlorate briquet.
  • the generator cell contains a metal baffle with a top or end wall fitting snugly in the can in spaced relation from the orificed end of the can and providing a compartment in the top of the can.
  • Two legs from the baffle grip diametrically opposed side walls of the briquet and provide an oxygen flow path between the side wall of the can and the legs to the compartment in the can above the baffle.
  • This compartment is filled with filter material effected to absorb any odors in oxygen en route to the orifice.
  • Additional mats are positioned between the top end of the briquet and the end wall of the baffle, and a bottom mat is provided between the bottom end of the briquet and the bottom of the can so that the briquet in effect is clamped between shock absorbing mats and embraced by the baffle to be centered in the can with ample oxygen flow paths between the briquet and the can. No insulation surrounds the briquet and heat radiation is uninhibited.
  • the mats between the briquet and the end wall of the baffle have central apertures overlying the ignition cone of the briquet and these apertures are filled with a loose powder first fire material which may be of the same formulation as the ignition cone.
  • the reduced leading edge of the briquet surrounding the ignition cone is desired to prevent a sudden outpouring of oxygen at the start of the reaction since this portion of the briquet surrounds the ignition cone and is rapidly heated.
  • the temperature tends to rise and accelerate the reaction but the reduced size of the trailing end of the briquet provides less cross sectional reaction area thereby reducing the available oxygen source even though the reaction rate may increase, and thus maintains a constant delivery rate of oxygen.
  • the mechanism for activating the oxygen flow generator requires a pointed ram 18 to first perforate the seal located in the center of the top wall of the generator and thence a forceful depressing of this ram to cause the release of the reaction initiation liquid from either the discipline of piston-cup storage, or fracturable vial storage.
  • the top web contains within its center a vertically movable button 16 which in a counter bore on its underside 35 holds the top 37 of the shaft 17 to the ram 18 concentrically centered and poised by a spring load 19 to keep the ram just above the top of the generator seal and in the center of the dispenser receiving port 20 which supports a heat resistant flexible seal 21 to contain and direct all oxygen flow from the generator into the plenum 22 or initial expansion chamber, and thence into the inlet tube 23 which leads down the inside wall of the dispenser to which it is fastened by an insulated grommet 24 and thence to a cooling coil 25 located at the bottom of the dispenser which utilizes the 'chimney effect' of airflow to provide cooling.
  • the plenum or initial expansion chamber also ports the oxygen by tube 26 to a pressure operated flow indicator 27 visible from the top of the dispenser.
  • the top 36 of the plenum 22 shares an alignment aperture 32 for the ram shaft, and the entire mechanism is affixed to the bottom of the top web by an appropriate quantity of concentrically arranged countersunk fasteners 28.
  • a number of concentrically, equidistant spring-like fingers 29 are affixed to the outside of the plenum and depend downward as a cage to align the oxygen generator spatially in the center of the dispenser.
  • the outlet tube 30 from the cooling coil, now carrying oxygen at ambient temperature, leads upward along the inside of the dispenser to which it is fastened 31 , and exits into a flexible delivery tubing 38 for attachment to a breathing mask, Figure 7.
  • the bottom web 2, Figure 5 is a light weight rigid material with alignment lugs 39 rising from each of the concentric legs 58 which provide dependable axial alignment for the cylindrical body, and a sturdy base for the complete dispenser.
  • the center hub 40 of the bottom web houses a compressible spring assembly 41 which clamps the oxygen generator 15 securely against the heat resistant flexible seal 21 of the dispenser receiving port 20 when the bottom web is closed and latched.
  • This assembly is held in the bottom web by a through-fastener 42 of which the top part of the thimble 43 is the retainer which is allowed to slide vertically to accommodate the presence or absence of an oxygen generator in the dispenser.
  • the dispenser cap 3 Figure 6 is of molded plastics with the same style of fluted or ridged exterior as the body of the dispenser and is finished in the same type of fiber-content paint.
  • the top wall of the cap bears a carrying strap-hasp 7 affixed through it, and the outside of the cap top is preferred for a product label 49.
  • the cap is equipped within a latch ramp 47 for the lock 33, and is drilled for fasteners 48 for attachment to the cylindrical body
  • the cap is of sufficient size to enable storage of the breathing mask, its elastic head band and the required length of flexible delivery tubing. When the mask is being used, the cap cannot be closed and therefore the continuous 'chimney effect' of the cooling airflow within the dispenser body is assured.
  • the breathing mask, Figure 7, is comprised of a flexible cone 50 with an additional flexible apron 51 to ensure more complete facial conformity.
  • the base of the mask contains a self sealing flexible diaphragm exhalation valve 52, and a spring loaded flexible diaphragm surge valve 53 to compensate for irregular or excessive breathing requirements.
  • the flexible delivery tubing 38 leading from the dispenser is attached to the mask cone 50 by fitting over a nipple 54 which is capable of swiveling through 360 degrees in order to accommodate any unusual delivery posture requirements.
  • the valve plate of the mask 55 provides diametrically opposed apertures 56 for introduction of the elastic headbands, which have not been included in the drawings.
  • the cap of the dispenser in which the breathing mask is stored can be equally effective when twist- fitted onto the top of the cylindrical body, of the dispenser by providing threads formed into the ends of the equally spaced fingers 14 above the top of the cylindrical body, which then engage matching threads formed into the equally spaced circumferentially located bosses inside of the cap. This will provide a twist attachment, or release, for the top of less than a full turn, and can be equipped within an anti-remove lock with push button control.
  • the flexible delivery tubing 38 can contain anywhere within its length an in-line ball/float on/off flow indicator for visual determination of positive flow by an operator /patient of the unit when in operation.

Abstract

Cette invention se rapporte à un distributeur personnel portatif léger, pour la distribution d'oxygène médicalement pur à la température et au débit appropriés, en vue de son inhalation directe. Ce distributeur comprend un générateur d'oxygène (15) permettant d'amorcer la création d'oxygène instantanément à partir d'une réaction chimique autonome de composés inertes à durée de conservation prolongée, sans l'apport de combustibles, dans un générateur totalement sûr et fiable. L'oxygène pénètre d'abord dans une chambre d'expansion (22). Le générateur d'oxygène est logé dans un corps de distributeur cylindrique (1), un espace annulaire étant formé entre le corps de distribution cylindrique et le générateur d'oxygène. Une membrure inférieure (2) fixée à la périphérie de la partie inférieure du corps de distributeur cylindrique permet à l'air provenant de l'extérieur du distributeur de pénétrer dans l'espace annulaire formé entre le corps de distribution cylindrique et le générateur d'oxygène et de sortir par la partie supérieure du corps de distributeur cylindrique. L'oxygène passe à travers un serpentin de refroidissement (25) et l'air s'écoulant à travers ledit espace annulaire refroidit le serpentin de refroidissement et l'oxygène s'écoulant à travers lui. Dans un mode de réalisation, le serpentin de refroidissement est formé à l'intérieur à l'espace annulaire entre le corps de distributeur cylindrique et le générateur d'oxygène et forme une hélice cylindrique.
